The Ball and Ring allows for a visible demonstration of the principles of the expansion of metals. When the ball is heated it will not pass through the ring, but when cooled the ball passes through the ring freely. The Ball and Ring are mounted on insulated plastic handles to protect your hands from the heat. Instructions included.
